Nothing, don't use them. I dislike them wherever I encounter them, I would detest them on my own server.<

Gee! That is really nice. Why is it that PHP has a lot of nice stuff. Do you know of anything done in Classic ASP that is open source and free or reasonably affordable?
I need something that has the same or similar licensing as does Snitz. I need something that I am free to alter the source code to make it do what I need it to do.
Thanks for the suggestion!
I've worked some with AdMentor, but the software does not allow it to be altered other than cosmetically to look like it is seamless with the site.<

Well, shoot! What are the commercial apps you recommend. I've been searching for a couple of days sorting through demos and license agreements as well as contacting authors about what I can and can not do.
I didn't understand the nature of coding for advertising via the web when I first started my quest for programs, but as I've been looking at the demos and seeing the complexity of it all, I am welcoming the idea of paying for a decent program and then modifying it (with permission, of course) to suit my needs.
Thank you for the help!

I use the following that I put together that shows random banners on every refresh of the page: Classic Snitz Demo
I think I have it packaged up somewhere, but if not, it would not take long to put together for a download. It has it's own Access 2000 DB.<

http://www.aspbanner.com/aspbanunlimited_v8.asp
I use this on http://www.coastercrazy.com/ in the forum topic pages and track detail pages at the topic using the jscript method to display the ads. It gives you a couple options on how to display the banner, jscript, asp tear, etc and shows impressions, can set it to expire by date, by ad impressions or something else I think. It's alright in my opinion and not horribly overpriced. You can let your customers login and view the impressions and ctr they have by day.<
